[Solved]OMV loss configuration: no share folders, no volume

Probably has a plugin installed that hasn't been ported to > 3.0.13. What is the output of: dpkg -l | grep openm

I don't see any bad plugin versions. Try:

omv-aptclean
omv-update

Still not working? Have you rebooted?

Is there more than one disk in the Physical Disks tab?

That is very strange. Everything looks ok from your pics. Can you post the output of: omv-showkey mntent

Ok. That is why nothing shows up in the volumes dropdown. Post the output of: cat /etc/fstab

DIdn't see it. People don't use the spoiler type very often

Not sure why your mntent entry is gone since it exists in fstab. Here is what I would do:

omv-mkconf fstab
reboot
The drive shouldn't be mounted now so mount the filesystem in the web interface
create new shared folders.
